Subject: AbstractMetaClasses now hold the instantiation types for the
 templates they implement.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

AbstractMetaClasses that are typedefs for template class instantiations
use to keep the template from where they derive, but didn't keep the
values used for the derivation. Now this is fixed, and with an unit test.
